Abstract
A fusion reactor requires a tritium (T) fueling system. The T fueling system consists of subsystems for fuel injection , vacuum pumping , fuel cleanup , isotope separation, fuel storage, blanket , and water detritiation. The fuel gas (T and deuterium (D)) is supplied by the fuel injection system and is exhausted by the vacuum pumping system. The exhausted gas is processed by the fuel cleanup system and the isotope separation system. Impurities, such as helium, water, and hydrogen (H), are removed by the above systems, and T and D are supplied again as the fuel gas through the storage system. The blanket system has a significant function that produces T from neutron and T breeder materials . The blanket system processes T thus produced and send it as fuel. A large amount of tritiated water is produced in a T-removal system and a coolant system. T in water is recovered by the water detritiation system and is sent as fuel again. In this chapter, the above T fueling system is described in detail. Some future R&D subjects in the T fueling system for a fusion reactor are also mentioned.
